One thing that I think would add a lot to your buildings would be "wooden framing." A lot of Mordheim buildings have "wooden beams" (popsicle sticks or stirring sticks) on the corners and sides of the buildings.

I recommend looking at Stew's Scenery for ideas. He did a great job with wooden framing.

My only critique is about the wall in the second picture. If a normal wall get's destroyed at the bottom like that, the rest of the wall will fall down, now stay up by being connected by a window frame.

Aaaah that explains it Hmmm... I guess it is not entirely false to qualify the Warhammer world as "steampunk" (after all there are steam tanks... ). But your scenery is more "cyberpunk" to me. Well, just a matter of taste I guess

Cheers!

PS: On a sidenote, when I think of steampunk (and I LOVE steampunk) I think more of this type of thing:

It looks good, but I'm not going to lie: It looks like a bottle and a cup glued onto cardboard.

What you need to do is hide what it actually is with a different texture. The ripples in the cup and Bottle give it away. I'd recommend getting spackle or thick paint, and filling in those gaps so it looks more like a smooth surface.

Although I think your idea was really good, I'm afraid the materials used are too obvious. As Ashton said: It really looks like what it is made of. It's more a Coke bottle than a Zeppelin, sorry

Alright, enough criticism, let's see how we can improve your model.

1) Using a coke bottle to make the body of the zeppelin is a good idea, but get rid of everything that reminds of a bottle, i.e. cut off the bottle neck and get rid of the cap! Find a way to make a round "nose" for your zeppelin. As Ashton said: cover the ripples with filler.

2) The passenger cabin should be more detailed. Think "building" rather than "box". Give it windows, a railing, a platform...

3) Look at historical pics of Zeppelins. Get inspiration.

4) Zeps usually had more than one huge propeller! Why? For steering. You cannot build a functional zeppelin that steers like a plane. The huge helium body prevents that.

You have to realise how ambitiious your project is. Building a Zeppelin is REALLY REALLY time consuming, albeit rewarding. You should either give it at least a month of construction, or maybe start with something simpler to get a little more experience.

Good luck!

PS: Oh and PLEASE PLEASE make a base that has texture (use PVA+Sand). Just plain cardboard is really ugly
